3/4-16 compression die

[josie]

I am going to try some thin wall stainless joints on my cues. What size tenon works best with wood for a 3/4"-16 compression die? I don't have live threading capabilities.

Where can I find this kind of info for furure reference? I googled it but did not find anything.

Does some sort of machinist handbook have that kind of info?

Thanks,

Eric

If you want a die, let me know, will sell it for good price. Going to live threading realllly soon and won't need. PM me if interested.

Thanks for the offer. Is your brass or aluminum? I bought the aluminum one but would prefer brass. If yours is brass I would be interested.

I mainly need to know the tenon size.

Thanks,

You may want to experiment with the same wood you are threading. The last one I did I ended up with my tennon @ Ø.720 or else I would rip the threads.

No thread relief at the bottom ? :smile:

Good thought. The collars that I have came with a very large internal chamfer.

Thanks for the help. I was planning on a little experimenting first but wanted a rough place to start.

Josie,

Another "trick" that was taught to me on this very forum is to use bees wax or paraffin on the tenon before you start to thread it. My first reaction was "WTH???? Glue won't stick to wax on the threaded tenon!!" I was assured "Try it, you'll like it!!"

I did and I do!!!

It's aluminum. The type of wood that you are threading is very important, and the advice to try it on smaller samples is very correct. The use of wax is too. Keep a notebook of the tenon sizes verses the woods used.. as it will vary quite greatly, based on my experiences.
I also recommend tapping your own collars, as I have found that quite a bit of suppliers sell collars that aren't quite the size they say it is. It may be the same thread count, but can be a very different overall tenon size or minor size, I have had issues with a certain supplier/maker over this before. Good luck,
Dave

Those threaded collars work very well, I use a .750 tenon. I don't use a compression die. I use a standard metal split die and lathe holder. Adjust the screw to open the die to it's max. to fit the holder, spray some T-9 on a paper towell and apply it to the wood, then thread by hand. I use the same method for the 5/8X18. The threads come out perfect with the correct tenon size. I don't like the compression dies because if you try to use the full size tenon, they rip. I do use the tenon threader for ferrules @.290. jmo

Thanks for all the the tips. I have done 5/8x11 with wax before.

I have a lathe die holder. I will give that a shot as well. It never crossed my mind to use a split die.

I tried them as a last resort after buying some stainless joints from Atlas, They are different than the ones I get from Jan mfg. Jan mfg, I could use the tenon threader from Chris Hightower and a .590 to .600 tenon, worked great. From Atlas, they wouldn't grab on anything less than a .615 tenon. on Split dies, That T-9 is the real key for me. The threads are clean.

I sent you a PM but others might like to know.

Do you use the round die and holder or the hex? I beleive you can get the split dies in both.

Do you use the aerosol t-9 or the drip bottles or does it matter?

Thanks again for the help. I am going to get set up to do it this way. Sounds like it works great.

I use the round holder, usually all split dies are round with an adjustment screw, not hex. I use the spray T-9, I use it on all my saws, jointer, etc, etc.,
use a brass rod or something to hold the holder but don't thread under power, if it stops quick, those set screws holding the die will get ya.
